Dominators @ 1066 BSOD

[Romo]

Hello guys !

I just bought myself a 2x2 Gb Corsair Dominator kit (CM2X2048-8500C5D, ver. 1,2) that was supposed to run at 1066 Mhz at default.

From the moment I first booted @ 1066 I keep getting BSODs, after few minutes, seconds after POST...no rules it just keeps crashing.

Memtest goes crazy of errors.

So I set speed to 800 Mhz and system is perfectly stable... memtest reports no arrors at all...

 

I really hope there is some BIOS tweak that I missed, because i don´t want to RMA.

It looks like per the link below to run at 1066 MHz. you need to set the BIOS to 5-5-5-15 2T @ 2.1 V. At the default 800 MHz. frequency it should run stable. OC'd stability/ability depends on your CPU/Mobo/RAM all being willing and able.

yes but 1066 mhz memory running at 1066 mhz is not overclocked memory.

why should I even consider it working stable at 800 mhz when my target frequency is 1066 mhz.

[trackrat]

I may have been wrong. I thought your CPU default RAM frequency was 800 MHz. Perhaps it will run both 800/1066 MHz. RAM frequencies? You may still need to manually set the RAM parameters in BIOS for the RAM to run at 1066 MHz. as this RAM typically requires 2.1 volts. Check the label on the RAM for the exact latency and voltage.

[Romo]

Yes, it is 2,1 V.

I set voltage to 2,1 latencies to 5 5 5 18 (or 15) but nothing seems to work.

How about more advanced memory settings like channel interleaving ?

Which setting should I use ?

If module was damaged would it be possible to show no errors in memtest at 800 mhz ?

I fixed the problem

Just set clock skew to advance 150 ps for both channels.

No errors in memtest at all :)

Hello!

I have Dominators (CM2X2048-8500C5D, ver. 1,2) and on the modules it is printed that voltage is 2.1 V

 

But everywhere on the internet, the voltage for verson 1.2 is 2.2 Volts.

And there are supposed to be D9 hanpicked chips, right ?

Not handpicked, and that list has been notoriously wrong for years. Use the list on the left. As for the voltage, use whatever the memory label states.

[Romo]

Use the list on the left.

 

what list ?

Could you please specify what is "to advance 150 ps for both channels" and how to practically do that?

 

Thanks,
